why is the fire extinguisher bad for us for ex if someone catch on fire why cant you just use the fire extinguisher on them insted of SDR
in fire extinguishers , CO2 gas is released , which puts off the fire . we , humans need oxygen to breathe , so if they are used on us ,we could even die due to lack of oxygen
The ABC dry chemical that comes out of the extinguisher is no where near as bad as being burned. The dry chemical dust is not toxic but it can coat your lungs just like any type of powder. The dry chemical is also not the best choice for using on a burning person because it does not cool the burning material. Even so the dry chemical can extinguish the flames, the person will continue to be burned by the heated material and clothing. The extinguisher you should use would be a AFFF foam or CAFS(compressed air foam) extinguisher. The water in foam cools the burning clothing (and person) and is more effective on the class A material that clothing is made of. The next best choice would be a water extinguisher filled with soapy water. By the chem help part of the question I take this as a lab question? If so you would just use the fire blanket to smother the flames on the person. Do not take it off until all the flames are extinguished. Then use the emergency shower to cool the peron's body if it was a large part of their body.
